OSCAR J. ZIEGLER, OF FREEPORT, ILLINOIS, ASSIGNOR TO STOVER MANUFACTURING COMPANY, OF FREEPORT, ILLINOIS, A CORPO- RATION OF ILLINOIS WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 693,481, dated. February 18, 1902. Application filed J anuary'4,-190 2 Serial No. 88,469. (No model.)

To all whom it may concern.-

zen of the-United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Wind-Wheels for Windmills, of which the followingis a specification.

. This invention has for its object the pro duction of a light strong wind-wheel constructed entirely of metal that can be packed and shipped in knockdown, so as to occupy but about one-fifth of the space required forthe Wheel when its parts are assembled and secured together; audit consists of certain combinations of parts especiallydevised to those ends, all as hereinafter fullydescribed,

and specifically pointed out, in the claims.

Referring to the accompanying drawings,

which form a part of this specification, Figure l is a front elevation of a wind-wheel embodying my invention. Fig. 2 isa peripheralview of the same. Fig. 3 is a section at the line 3 3 in Fig. 1 of parts there shown. Fig. tis an isometrical detailed view of a section broken out of the complete wheel. Fig. 5 is a view of the parts of the wheel in knockdown ready to be shipped.

Like letters of reference indicate corresponding parts throughout the several views. A is a hub providd'with radial semimortises A A to receive the inner ends of the spokes of the wheel.

B represents outer bents, comprising parallel pieces B, curved edgewise in form of seg-' ments of a circle, secured together by means of double knees B and doublebraces B having apertures 13 between-them.

0 represents inner bents, comprising parallel pieces 0, curveded'gewise in form of segments of a circle of less diameter than that formed by the bents B, secured together by means of double kneesC and double braces O having apertures 0 between them. The parts comprising the bents B and O are firmly secured together, preferably by means of rivets.

D represents furcated spokes having double knees D connecting their furcationsD Beit known that I, OSCAR J. ZIEGLER, aciti- D near their innerends.

F, Fig. 2, represents double knees, for se- Fig. 5 together, the bents B are bolted together to form the outer and the bents O to .form the inner circular wheelfrarne, Fig. 1. The spokes D are next bolted to the outer and inner circular Wheel-frames, Fig. 1, and

their furcated ends D D are thereafter bolted into thesemimortises A A in the hub A. The bats E are thenslid into the apertures 13 C between the double braces B C and bolted therein, leaving the wheel ready to be mountedfor use.

The parts of thewheel are shown assembled and wired together in parcels in Fig. 5 ready for shipment. V

Wind-wheels of the. construction shown are especially adapted for shipment abroad, for which freight charges are based on the cubic space occupied by the articles shipped.

To put the parts of the wheel shown in Having thus described my invention, what I I claim as new, and desire to secure by Letters Patent, is' y 1. In a wind-whee] for windmills, in combination, a hub, an outer wheel-frame formed comprising parallel piecescurved, edgewise, in form of segments of a circle of less diameter than the outer wheel-frame"secured together by means of double knees, and double braces having apertures between of bents comprisingparallel pieces-curved,

them, spokes, securing the outer and inner y wheel-frames together, and to the hub by their furcated ends, and bats, inserted into the ap ertures between the double braces of the outer and inner wheel-rims, substantially as and for the purpose specified. I

2. In combination, a hub A, provided with ner ends of the spokes of the wheel, an outer wheel-frame formed of bents B comprising parallel pieces B--curved, edgewise, in form of segments of a circle-secured together by means of double knees B and double braces I n n name to this specification 1n the presence of 20 B having apertures B between them, an inner wheel-frame formed of benis C comprising parallel pieces G'curved, edgewise, in form of segments of a circle of less diameter than the outer whee1-framesecured together by means of double knees C and double braces C having apertures 0 between them,

furcated. spokes D, securing the outer and inner wheel-frames together and themselves 15 secured, by their furcations D D to the semimortises A A in the hub A, substantially as and for the purpose specified.

In testimony whereof I have signed my two subscribing witnesses.

OSCAR J. ZIEGLER.
